When closing a popup, notify the platform window, so that the mcu
backend can remember that region and start the dirty region with it.
Also, free all the rendering cache items of deleted items, to avoid accidental re-use
when re-opening a popup.
This reverts commit faf07ea237 as it
breaks dependency tracking with the partial renderer. The effect is that
the mcu printer demo (in release?) doesn't react to input events
anymore. They are delivered by the redraw tracker doesn't get notified.
This also separates the blend-to-screen part of render_layer into a
helper function, as that will be useful in the future with public layer
elements.
Relates to #725
Delegate the decision how to implement the Clip element entirely into the backend,
where the GL backend can now explicitly render
children into a layer, instead of the hack with a layer in the renderer's
state and the extra save/restore pair.
The render function now takes a self_rc and returns a enum that permits
the implementation to handle rendering of children on its own and
thus make the caller skip that traversal step.
Instead of using the generic visitor, call `visit_children_item` directly on the Component.
This way we avoid the RefCell for the renderer and this will make it
easier to introduce items that decide to render the children themselves, with
their own property tracker.
Move "internal" crates into the `internal` directory. This first batch
includes most of sixtyfps_runtime but leaves the rendering backends
alone for now.
pre-commit applied some cleanups to the moved files:
- Consistent newline at end of file policy
- trimming trailing whitespace
- Formatting Cargo.toml files.
